Answer:
Explanation:
Hi there,
To get started, please recall what heating curves are, latent heat, and enthalpy of phase changes (vaporization, fusion).
In a heating curve for ice water, temperature is the dependent variable (y-axis) and heat or time elapsed is independent variable (x-axis). There are three sloped portions. These sloped portions are showing where the <u>mixture is not changing phase, and is in a specific phase.</u> (solid first, then liquid then gas).
The reason is because the addition of more heat in time is causing the temperature to rise, so the mixture is getting "hotter." The temperature is still rising, yet the mixture is still in the current phase (depending on where you are referencing on the curve).
The two leveled portions are the process of melting (first leveled) and boiling (second leveled). The reason they are horizontal is because the addition of heat is not causing temperature to go up. The molecules are in the process of distributing heat in a different form by changing the mixtures entire structure (AKA phase), and so they are flat because the average kinetic energy from heat is being used change phase.

3 x 10⁸ = f x 6.5 x 10⁻⁷
f(red) = 4.6 x 10¹⁴ Hz
The frequency of the second wave is higher, meaning it has a lower wavelength and greater energy than that of red light.
Answer:
ten octaves
Explanation:
Answer. One octave, corresponding to a halving of the upper frequency limit. Although human hearing covers a range of, say, ten octaves at best, seven of these octaves cover the bottom eighth of the range, from 20 Hz up to 2500 Hz, which corresponds roughly to the pitch range from E♭0 to E♭7 (Figure 26).
